Additional Dwelling Unit and Multi-Plex Housing Incentive Program
The Additional Dwelling Unit and Multi-Plex Housing Incentive Program is intended to provide a financial incentive to help offset eligible costs related to the creation of Additional Dwelling Units or Garden Suites within, or on the same property as, new or existing low-density houses or the creation of multi-plex developments with six (6) or fewer Dwelling Units. As of October 9th, 2025, the grant value and requirements were amended by the Housing Sustainability Investment Roadmap (HSIR) Executive Committee.
The value of the Grant is 70 per cent of Eligible Costs, to a maximum of $40,000 per Eligible Unit(s). The Grant is structured in two payments:
- The first advance is 20% of the total estimated grant amount, to a maximum of $8,000 per Eligible Unit(s). Due to the timing of this payment, the first advance is calculated using a contractor’s estimate for total Eligible Costs (20% of 70% of estimated Eligible Costs).
- The second advance will be calculated based on actual Eligible Costs incurred and is payable upon occupancy permit issuance. This advance is up to 70% of Eligible Costs incurred, less the amount of the first advance.
- In all cases, the total Grant provided, the sum of both advances, will not exceed $40,000.
